From the results recorded it was identified that activity A and C had exothermic reactions‚ whilst activity B had an endothermic reaction. Each of the activities had initially begun with 23.4/8/9oC‚ however‚ within one minute of adding the 2nd reactants‚ the results began showing‚ as seen from the graph. Activity A and C had risen in temperature‚ with A gaining 4oC and in total of 2 minutes having the temperature of 27.9oC along with C increasing by 2.2oC and within 2 minutes of the experiment having

Concentration‚ Along with Varying Temperature and pH-Balanced Environments on the Enzyme-Catalyzed Reaction of pNPP Abstract: Introduction: Many of the chemical reactions‚ which take place in in living things are controlled by enzymes. In such cases‚ the enzyme is a protein in the cell which lowers the activation energy of a catalyzed reaction‚ which serves to increase the rate of the reaction. Alkaline phosphatase is made throughout the body. Its function is to remove phosphate groups

Constant of an Unknown Ester Hydrolysis Reaction Abstract The experiments to follow determined that the equilibrium concentrations of the reaction: ester + water ↔ alcohol + acid‚ are equal to 0.0363 moles of ester‚ 0.2852 moles of water‚ and 0.0268 moles each of alcohol and acid. Using this information the equilibrium constant was determined to be 0.06938. 1. Introduction In this lab the equilibrium constant‚ Kc‚ for the acid catalyzed reaction between an unknown ester and water

Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

In order to first perform the reaction‚ 1.5 mL of 4-methylcyclohexanol was added to a pre-weighed 5mL conical vial. The conical vial was then weighed to find the actual mass of 4-methylcycloheaxanol. Then‚ 0.4mL of 85% phosphoric acid was added to the conical vial using a plastic pipet. Six drops of concentrated sulfuric acid was then added to the vial using a glass pipet. A spin vane was then added before adding the Hickman head‚ water condenser and a drying tube packed with calcium chloride to

Plasmid DNA purification systems to isolate the plasmid DNA. Indeed‚ the bacterial cells were removed from the liquid broth and were resuspended in the lysis solution. They were rinsed in a buffer before going through centrifugation. - Polymerase Chain Reaction (PCR): The isolation done‚ the Drosophila cDNA located in the plasmid DNA was amplified. The PCR was used to determine the size of the cDNA inserted into the plasmid DNA. One tube (A) contained the plasmid DNA A with the PCR master mix‚ the other

“Love Your Fat Self” Response Paper In “Love Your Fat Self” (2008)‚ Courtney Martin uses her obese friend as an example of someone who is amazing in every other way‚ but seen as flawed because she’s fat. Her point is to make society take responsibility for its part in the problem with obesity. She mentions that being fat is pretty much always seen as a physical health problem‚ and that most people‚ including the doctors that attempt to treat overweight people‚ don’t know the psychology behind

Call us sick‚ but somehow‚ dragging a legless office worker across a wild obstacle course from the back of a Segway in Happy Wheels is... well‚ a lot of fun. More fun than it probably should be. Happy Wheels is all about two things: ridiculous obstacle courses and its consistent damage system. The damage system is what really sets it apart from similar games. The obstacle courses mix a little bit of traditional platform gaming with some puzzle and racer elements‚ but it’s the injuries your racers

purpose of this lab was to find the theoretical and experimental percentage yields of the double displacement reaction between the solutions Lead (II) Nitrate (PbNO3) and Potassium Iodide (KI). It is important to obtain amounts of Lead (II) Nitrate and Potassium Iodide as close to 1.44g as possible. This reaction creates Lead (II) Iodide and Potassium Nitrate. The precipitate during this reaction is Lead (II) Iodide. The balanced equation is Pb(NO3)2 + 2KI= PbI2 + 2KNO3. In this lab the Lead (II) Iodide
